ARMATURE CONVEYING APPARATUS Filed June 29, 1928 2 Sheets-Sheet 2 g five Patented A 1930 UNITED STATES PATENT OFFICE RUSSELL W. BAKER, F ANDERSON, INDIANA, ASSIGNOB TO DELCO-REMY CORPORA- 'IION, OF DAYTON, OHIO, A CORPORATION OF DELAWARE ARMATURE-CONVEYING APPARATUS Application fi led June 29,

This invention relates to apparatus for conveying articles through a liquid bath and particularly for conveying the armatures of dynamo electric machines through a bath of varnish used to coat the armature wind- %)ne object of the present invention is to provide a simple and durable apparatus which will convey dynamo armatures through a varnish bath and whichwill protect the ends of the armature shafts from the varnish.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of embodiment of the present invention is clearly shown.

In the drawings: 7 i

Fig. 1 is a fragmentary diagrammatic view of the conveying apparatus embodying the present invention.

Fig. 2 is a view on an enlarged scale of an armature suspended from one of the hangers of the conveyor shown in Fig. 1.

Figs. 3 and 4 are plan and side views respectively of a modified form of hanger sleeve. j

Figs. 5 and 6 are plan and side views respectively of a still further modified form of hanger sleeve. 7

The particular form of armature to which the present invention is adapted to be used is one comprising a shaft 20 carrymg a commutator 21 connected with armaturewlndings 22 wound upon a core 23 also attached to the shaft 20. Referring to Fig. 2, the armature hanger is provided by bending a piece of wire so as to provide an intermediate loop 24 which surrounds the commutator 21 and which has a hook 25 received by anrannular groove 26 in a ring or collar 27 and with a portion 28 adapted to extend alongside the armature core 23 and terminatlng in a hook 29 adapted to engage any of a plurality of hooks 30 integral with a hanger cup or sleeve 31 providing a central socket for receiving the lower end of the armature shaft 20.

The armature hanger conveyor is provided 1928. Serial No. zeaae 42. It will-be understood that the shaft 42 supports a similar sprocket-41 for supporting another chain 40 parallel to the one shown in thedrawing. The two chains 40 support between them a plurality of rods or u tubes 43 each carrying 'a plurality of collars 27 and hangershaving commutator 'embracing loops 24 and hooks 29.

. Before the armature is 'supportedon the conveyor for movement intothe bath of varnish supported in a vat 50- the end of the ar mature shaft whichis emerged is coated with oil before the protectingsleeve 31 'is placed upon it. Then the' assembled sleeve and armature are I assembled with the hanger as shown in Figs. 1 and 2. The hook 129 co operateswith' the sleeve 31 to support'the armature shaft by its lower end portion and the loop 24 cooperateswith'the commutator 21 so as tormaintain the armature in substantially vertical position." The hangers are pivotally supported upon the cross tubes 43 so that they will remain upright as they pass into andout ofthe varnish vat 50. It has been the practice to convey the armatures from the varnish vat into a varnish drying oven. After being conveyed from the drying oven, th'e armatures are removed from the hangers and the protecting sleeves 31 are removed from the armatures.

As armatures may varyin length of the armature core, the sleeve 31 may be provided with a plurality of hooks 30 so that the sleeve 31 may be adapted to support thearmature at the proper distance so as to locate the commutator 21 within the loop 24 and at such a distance below the conveyor that all portions of the armature windings willbe submerged into the varnish bath. Figs. 4-

and 16 show other forms of hanger sleeves 'which may be used with the same hangers which support the sleeves 31 shown in Figs. 1 and 2. The hanger sleeve is constructed so as to be adapted to support armatures having shafts varying in length and in diameter as well as to be adapted to support armature cores varying in length.

While the form of embodiment of the present invention as herein disclosed, constitutes a preferred form, it is to be understood that 'other for ns Inightbe adopted, allcoming within the scope of the claims-which follow. 7
